Abstract

The heated external driving mirror has the mirror (2) fitted into a housing (1) and with the space inside the housing filled with a conducting layer (3) in which connecting electrodes are embedded. The electrodes (8) provide the heating current connection for even heating of the mirror. The back of the mirror and the inside of the housing are coated with an insulating layer so that short circuits are prevented. The backing layer serves also as a damping layer. The heater design does not damage the mirror or housing.

Description

AUSSENSPIEGEL FUR KRAFTFAHRZEUGE EXTERIOR MIRROR FOR VEHICLES

Die Erfindung betrifft einen Außenspiegel für Kraftfahrzeuge gemäß dem Oberbegriff des Anspruches 1.The invention relates to an exterior mirror for motor vehicles according to the preamble of claim 1.

Ein derartiger Spiegel wird auch in der älteren Anmeldung P 27 19 174.8 der Anmelderin beschrieben. Dort ist die mit einer Isolierschicht versehene Rückseite des Spiegelglases mit einer Widerstandsschicht bedeckt, die sich zwischen zwei Stromzuführungselektroden erstreckt. Dort bedeckt eine Isolierschicht die Widersandsschicht, damit die Widerstandsschicht von der Spiralfeder, welche wischen dem Gehäuse und dem Spiegelglas angeordnet ist, nicht zerstört wird.Such a mirror is also in the earlier application P 27 19 174.8 of the applicant. There is the one provided with an insulating layer The back of the mirror glass is covered with a resistive layer that extends between extends two power supply electrodes. There an insulating layer covers the resistance layer, thus the resistance layer from the coil spring, which wipe the housing and the mirror glass is arranged, is not destroyed.

Der Erfindung liegt die Aufgabe zugrunde, einen Außenspiegel der eingangs genannten Art heizbar zu machen.The invention is based on the object of providing an exterior mirror of the initially specified to make said type heatable.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Bevorzugte Ausbildungen der Erfindung sind in den Unteransprüchen beschrieben.According to the invention, this object is achieved by the characterizing features of claim 1 solved. Preferred developments of the invention are in the subclaims described.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Herstellung einfacher ist,weil die Spiralfeder und das Aufbringen einer Widerstandsschicht und der Isolnerschicht auf der Rückseite des Spiegelglases entfallen sannP Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt Der Innenraum des Spiegels zwischen dem isolierenden Gehäuse 1 und dem isolierenden Spiegelglas 2 ist mit einem elektrisch leitenden Kunststoffschaum 3 auscefüllt. Im Kunststoffschaum 3 sind zwei Elektroden 8 angeordnet, die mit Zuleitungsdrähten verbunden sina, die durch die Öffnung 6 und durch den Befestigungsarm 5 hindurchreichen und mit der Stromquelle des Kraftfahrzeuges verbunden sind.The advantages achieved with the invention are in particular: that the manufacture is easier because the spiral spring and applying a resistance layer and the insulating layer on the back of the mirror glass omitted where one embodiment of the invention is shown schematically in the drawing The interior of the mirror between the insulating housing 1 and the insulating mirror glass 2 is covered with an electrically conductive plastic foam 3 filled out. In the plastic foam 3 two electrodes 8 are arranged with lead wires connected sina, which extend through the opening 6 and through the fastening arm 5 and are connected to the power source of the motor vehicle.

Der Kunststoffschaum 3 kann in das Innere des Spiegels eincespritzt werden und denach ausnärten, oder er kann ein vorgefertigtes Formteil sein, das d' e Elektroden 7 bereits vor der Montage des Spiegels enthält.The plastic foam 3 can be injected into the interior of the mirror and then cure, or it can be a prefabricated molding that d 'e electrodes 7 already contains before the assembly of the mirror.

Die Formmasse 3 ist elastisch und drückt das Spiegelglas 2 über einen elastischen ringförmigen wulst 4 gegen die otrdelung 7 am Rand des Spiegelgehäuses 1.The molding compound 3 is elastic and presses the mirror glass 2 over a elastic annular bead 4 against the otrdelung 7 on the edge of the mirror housing 1.

Es ist auch möglich, ein metallisches Gehäuse 1 zu verwenden, das an der Innenoberfläche bis auf einen bestImmten Flächenbereich mit einer elektrisch isolierenden Schicht bedeckt ist.It is also possible to use a metallic housing 1 that on the inner surface except for a certain surface area with an electrical insulating layer is covered.

Dann wirkt dieser freie Flächenbereich als auf Massepotential liegende erste Elektrode und im Kunststoffschaumkörper 3 braucht nur eine zweite Eiektrode 8 mit einer Zuleitung angeordnet zu sein.This free surface area then acts as being at ground potential first electrode and in the plastic foam body 3 only needs a second electrode 8 to be arranged with a supply line.
